Description

Initially when UI grid loads the data, I want to show first row as selected. I found one issue - I am calling this public API
$scope.gridApi.selection.selectRow(row);

This method internally calls toggleRowSelection and multiSelect, noUnselect are false in my case. toggleRowSelection: function (grid, row, evt, multiSelect, noUnselect)

var selected = row.isSelected; // undefined afer loading the grid

In the above method, i am able to see selected value is "undefined" after initializing the grid. Therefore, code goes into following if block and which clears the row. if (!multiSelect && !selected) However, the code should first check whether is it undefined or not. Either, there should be some different API for selecting row. Using togle is issue.

Research direction
Investigate the source file for row selection logic, likely in 'src/features/selection/selection.js' or similar. Locate the toggleRowSelection function and examine the condition 'if (!multiSelect && !selected)' where selected could be undefined when a row is newly loaded. The fix should handle the undefined case by treating it as not selected, ensuring that selectRow API works as expected. Check for any existing PRs or comments addressing this issue.
